After the fuel handling during nuclearpower plant (NPP) overhaul, the refueling pools are required to be decontaminated due to the need for maintenance work. The application of a new technology offoam at Ningde NPP is presented in this regard. It shows that the foam technology has greatly promoted collective dose control, loose contamination removal andradioactive waste minimization, compared with conventional decontamination processes.

Radiation therapy is one of the main methods for the treatment of tumor. However, radiotherapy of tumors in differentparts of the head and neck, chest and abdomen in patients may bring about radiation injury to normal tissues around the site, which in turn cause a lot of sideeffects. With radiodermatitis, radiation-induced oral mucositis, radiation pneumonitis and radiation proctitis taken as examples, the clinical nursing researchstatus of radiation injury after radiotherapy in different parts of tumor patients is introduced.

Uncertainty Evaluation of Polonium-210 Analysis in Aerosol Samples

Li Jun, Xiao Peng, Zhang Wenqian, Yu Zhengwei

RADIATION PROTECTION BULLETIN. 2017, 37(5):  28-31. 

Abstract ( 27 )

Polonium-210, an important natural radionuclide, attracts extensive attention of environmental monitors due to its widely presence in the biosphere and extreme toxicity. In order to determine the uncertainty of polonium-210 analysis in aerosol, the evaluation process of uncertainty was introduced, and the contribution of each component to uncertainty wasdiscussed. The results show that the uncertainty is mainly from the sampling volume of aerosol samples, the preparation and transfer of tracer solution, the measurement by α counting and other aspects.

In accordance with the requirements ofrelevant national standards, a project of four diagnostic medical apparatus ata hospital was evaluated for acceptance, with respect to environmental protection monitoring and the radiological protection effect in the workplace. Based on dose data of measurement points, the annual doses for radiation staff and publicare calculated to be 1.8 mSv/a and 0.004 8 mSv/a, respectively, which are both lower than the relevant constraint values. It turns out that the project is compliance with national standards, concerning the radiation level and machine room radiation protection devices, and the conditions of completion acceptance are met.
